URL Protocol Handler Registration for PWAs

Feature: URL Protocol Handler Registration for PWAs

Enable web applications to register themselves as handlers of custom URL protocols/schemes using their installation manifest.

Motivation

Native applications often register themselves as protocol handlers to increase discoverability and usage. While websites currently have this ability to register to handle schemes via registerProtocolHandler(), it is desirable to have web apps be first-class citizens and be launched directly when a custom-scheme link is invoked.
